ALEXANDER lV. KRUMM, OF CINCINNATI, OHIO.

ATOMIZER.

SPECIFICATION forming part of Letters Patent No. 560,507, dated May 19,1896.

Application filed March l 8 l 8 9 6.

To all whom it may concern:

Be it kn own that I, ALEXANDER W. KRUMM, a subject of the Emperor ofGermany, residing at Cincinnati, in the county of Hamilton and State ofOhio, have invented certain new and useful Improvements in Atomizers, ofwhich the following is a specification.

My invention relates to an improvement in atomizers or apparatus forejecting or diffusing liquid medicaments in spray or vapor; and itconsists in the novel features of construction hereinafter fullydescribed, and particularly pointed out in the claim.

In the accompanying drawings, Figure lis a broken sectional elevation ofmy invention complete, showing a hand compressing-bulb forming partthereof; Fig. 2, an elevation of an atomizing-tube embodying myimprovement proper broken off at its upper portion and omitting thevessel and bulb seen in Fig. l; Fig. 3, a bottom or lower end View ofFig. 2; Fig. 4, a transverse horizontal section on dotted line Fig. 2 5and Fig. 5, a sectional plan on dotted line y J of Fig. 2.

A represents any suitable receptacle or vessel for holding the medicineto be vaporized or atomized. In this instance I show my preferred formof vessel, which is. simply a cylindrical glass bottle having ascrew-threaded neck a and a corresponding screw-threaded metal cap a',adapted to removably fit thereon, with a cork or other suitable washeror gasket a2 interposed to secure the desired air-tight joint.

My atomizing-tube is preferably made of hard rubber and suspended withinthe vessel A, with its upper end tightly fitting within a collar orshort tube B, centrally mounted in the cap a and its lower endterminating slightly above the bottom of said vessel. Thisautomizing-tube is composed of a vertical tube or shell C, aclosely-fitting plug D within said shell, and a short sleeve or jacketE, fitting over the lower end of said shell.

d d represent a pair of longitudinal grooves readily constructed alongthe plug D, beginning at its upper end and continuing almost to itsopposite lower end and forming passages within the surrounding tube orshell C for the air or steam blast forced into them by means of the bulbor air-supplying device F, which latter has va flexible tube connectionf with Serial No. 583,831. (No model.)

the upper end of the atomizer-tube, which projects beyond the cap nippleor collar B.

c c represent short flattened faces constructed along the outer face ofshell C within the vertical limits of sleeve E, and b b are smalltransverse holes made in said shell at a point j ust above the lowerends of the passages formed by the vertical grooves d d aforesaid and inline with the flattened faces c c.

e e are transverse holes made in the jacket E, registering horizontallywith the holes b and having their outer portions preferably iared orexpanded, as best seen in Figs. l and Il, for the better diffusion ofthe spray or vapor therefrom.

G represents an upright nipple or vaporoutlet in the cap a', mounted toone side the central collar and provided with a flexible discharge ordelivery tube g, having the customary nozzle g.

In the operation of my apparatus the medicinal substance to be vaporizedis placed in the vessel to a level below the holes b e in theatomizing-tube. Atmospheric air or other blast is forced by means of thebulb or other suitable pump F down the passages d and across t-hetransverse holes @passages c, and exit-orifices e into the vessel,causing a suction of the medicinal fluid up said passages c to charge orimpregnate said blast therewith and carrying or forcing it in minute orexceedingly kne spray or vapor from the Haring orifices e to pass upwardto the vapor receiving and delivering tube, and thence through thenozzle to the patient or other desired destination.

It is obvious that but one air-passage d, one hole b, one flattened faceto form a channel c, and one vapor-exit orifice e could be provided inmy atomizer-tube instead of the double set above described and shown inthe drawings, or more than two of each could be constructed therein andmore discharge-nozzles used to suit the purpose or use desired, amultiple of them being preferable in order to produce a greater supplyof vapor to accommodate a number of patients simultaneously or toimpregnate the surrounding air to a greater degree.

I claim In an atomizer, a vaporizing-tube composed of a central,internal plug having one or more IOO grooves d; a tube or shell fittingover or surrounding said plug, and having one or more transverse holes Dand short, vertical flatten ed faces c constructed at its lower end tocoincide with one or more of said grooves d; and a sleeve or jacketsurrounding said shell at its lower end, from a point just above theupper end of channels c; and having one or more outwardly-flaringvapor-exit orifices registering with said holes b; the Whole beingsuspended within a suitable receptacle or vessel,
